Blue Monkey

The Blue Monkey (Cercopithecus mitis) is native to Central and East Africa, ranging from the upper Congo River basin east to the East African Rift and south to northern Angola and Zambia.
Despite its name, the blue monkey is not noticeably blue; it has little hair on its face, and this does sometimes give a blue appearance. It is mainly olive or grey apart from the face (which is dark with a pale or yellowish patch on the forehead).
